摘要： A system for forming a bulk material having insulated boundaries from a metal material and a source of an insulating material is provided. The system includes a heating device, a deposition device, a coating device, and a support configured to support the bulk material. The heating device heats the metal material to form particles having a softened or molten state and the coating device coats the metal material with the insulating material from the source and the deposition device deposits particles of the metal material in the softened or molten state on the support to form the bulk material having insulated boundaries.

摘要： A bulk material formed on a surface, the bulk material including a plurality of adhered domains of metal material, substantially all of the domains of the plurality of domains of metal material separated by a predetermined layer of high resistivity insulating material. A first portion of the plurality of domains forms a surface. A second portion of the plurality of domains includes successive domains of metal material progressing from the first portion. Substantially all of the domains in the successive domains each include a first surface and a second surface, the first surface opposing the second surface, the second surface conforming to a shape of progressed domains, and a majority of the domains in the successive domains in the second portion having the first surface comprising a substantially convex surface and the second surface comprising one or more substantially concave surfaces.

摘要： A system for forming a soft magnetic bulk material of a motor stator from a magnetic material and a source of insulating material, the system comprising: a support; a heating device; a deposition device; and an indexing mask subsystem. The support is configured to support the soft magnetic bulk material of the motor stator. The heating device is for heating the magnetic material to form particles having a softened state. The deposition device is for depositing successive layers of particles of the magnetic material in the softened state on the support. The indexing mask subsystem is configured as a first negative of an inner shape of the motor stator and a second negative of an outer shape of the motor stator. The indexing mask subsystem is located between the deposition device and the support and indexed relative to the support upon deposition of the successive layers to selectively block the successive layers of particles of the magnetic material in the softened state from being deposited on the support, thus forming the soft magnetic bulk material of the motor stator as the inner shape of the motor stator and the outer shape of the motor stator on the support. The soft magnetic bulk material has a plurality of adhered domains of magnetic material, wherein substantially all of the domains of magnetic material are separated by a predetermined layer of high resistivity insulating material.

摘要： A system for forming a soft magnetic bulk material of a predetermined shape from a magnetic material and a source of insulating material. The systems has a heating device; a deposition device; a support configured to support the soft magnetic bulk material of the predetermined shape; and a mask configured as a negative of at least a portion of the predetermined shape. The heating device heats the magnetic material to form particles having a softened state and wherein the deposition device deposits successive layers of particles of the magnetic material in the softened state on the support with the mask located between the deposition device and the support. The mask is indexed to a position relative to the support upon deposition of the successive layers. The mask selectively blocks the successive layers of particles of the magnetic material in the softened state from being deposited on the support forming the soft magnetic bulk material of a predetermined shape on the support.
